Application fil'edFebruary 12, 1917. Serial No. 148,205.

To all whom it may concern Be it known that I, lVILLIAM F, WILSON, acitizen of the United States, residing at the city and county of Denverand State of Colorado, have invented certain new and useful Improvementsin Combination Hammers and Tool-Holders; and I do declare the followingto be a full, clear, and exact de-' scription of the invention, such aswill enable others skilled in the art towhich it apperta-ins to make anduse the same, reference being "had to the accompanying drawings, and tothe characters of reference marked thereon, which form a part of thisspecification.

l ly invention relates to improvements in tools of the hammer class andof the type requiring a comparatively sharp edge or point arrangcdat'the extremity opposite the hammer or nail driving member. Thisconstruction is exceedingly well adapted for use as a brick hammer sincetools of this class require a relatively sharp point or edge in order tobreak the bricks as may be required in cases where a full sized brick isnot usable. In :order that this work may be done with reasonableaccuracy, it is important that the edge of the hammeremployed in cuttingor breaking the brick, shall be comparatively sharp. Usually abricklayer will dull the point-ofhis hammer every day thus making itnecessary to send the hammer daily to the machine shop for sharpeningpurposes. My improvement provides for readily removing the cutting toolor blade from the body or holding member of the hammer and thesubstitution of another tool or blade, thus ;mak' ing it practicable forthe mechanic to employ a single hammer body with an indefinite number-oftools or blades and making it practicable to send only these blades orpoints to the shop to be sharpened. Hence where my improvement is used,it is practicable for the workman to have a number of the blades at handready for substitution as circumstances may require. This islmuchcheaper for the workman, and enables him to do .much better work sincehe will always have the advantage of having a sharp blade for use, thusenabling him to do better and .more accurate work in cutting the bricksas occasion may require.

It should be explained that my improvement is equally advantageous inthe case of picks or other tools which require relatively sharp bladesor points. In all such cases'the body or hammer head, becomes the holderfor the tool, point or blade, the latter being securely held in placethrough the medium of a relatively stifi leaf spring which normally actsupon the blade to hold it securely in place. This spring, however, maybe actuated to cause it to release the blade, by laying the lowersurface of the outer end of the blade upon a hard smooth surface, andthen rocking the hammer head forwardly, whereby the blade acts as alever in moving the holding extremity of the spring outwardly, farenough to permit the placing of a pin or nail through the outerextremity of the spring which is provided with an'eye for the purpose,the opposite ends of the pin resting upon the outer edges of two sidewalls with which the holder is provided, the latter being cut away orgrooved between these walls :to make room for the holding spring and theinner portion of the blade or point. After this is done, the dull blademaybe removed "and a sharp blade substituted, after which by repeatingthe operation just described, the outer end of the spring may beactuated to release or loosen the nail or pin, thus making it easilyremovable, after which the spring acts upon the blade to hold itsecurely in place. My impr'vement may also be advantageously used in thecase of axes, hatchets, and all similar tools if desired, sincein orderto employ my improvement it will only be necesto make a relatively thinflat portion which may e inserted in the holder whereby it is inposition to be engaged by the spring of my improvement.

Having briefly outlined my improved construction, I will proceed todescribe the same in detail, reference being made to the accompanyingdrawing, in which is illus trated an embodiment thereof. In this drawingFigure 1 is an elevation of a-brick hammer equipped with my improvement,the

head and blade of the --hammer being shown in central longitudinalsection.

Fig. 2 is a similar view of the hammer, shown however, in position toactuate the sprin in order to inserta pin 'or nail for supporting thespring in position to make the removability of one blade and thesubstitution of another, practicable.

Fig. 3 is a section taken on the line 8-3 Fig. 2.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate the head of a brick hammer or other similartool as heretofore outlined. This head is provided with an opening inwhich is inserted a handle 6 of the usual type. The nail drivingextremity 7 of the hammer or other tool may be of any suitable orordinary construction. Extending from. the eye and on the opposite sideof the handle from the head member 7, is the holder member 8 in which isformed a relatively deep groove or cavity 9 on opposite sides of whichare walls 10. This groove or cavity is closed at its rear extremity asshown at 12, but open at its opposite extremity as shown at 13. Thecavity is of sufiicient width to receive the inner extremity or portion1a of a cutting blade or member 15 having a portion 16 extending beyondthe holder member and having a relatively sharp free extremity 17. Thisblade member 16 is normally held securely in place by means of arelatively stiff leaf spring 18 which is located in the cavity 9, itsinner extremity being curved as shown at 19 to engage a pin or abutment20 whose opposite extremities are anchored in the walls 10 of the holdermember. Between the inner and outer extremities of this spring 18, islocated a second pin 2a which extends transversely of the cavity 9, itsextremities being also anchored or supported on the side walls 10 of theholder member. The outer or forward extremity 21 of the spring is curvedto form a partial eye, this extremity being bent outwardly whereby it isadapted to receive a pin or nail 25, when the outer extremity of thespring is forced upwardly in the cavity 9, far enough to permit theinsertion of a pin transversely through the eye and allow the oppositeextremities of the latter to rest upon the edges 22 of the side walls 10of the holder. When this is done the forward extremity of the cavity isopened below the corresponding extremity of the spring a sutlicientdistance to permit the ready removal of a dull blade member 15 and theinsertion of a sharp one, whenever occasion for such removal andsubstitution may exist.

Normally the outer or eye extremity 21 of the spring 18, acts upon theblade member 16 to hold the latter securely in place. When, however, itmay be necessary to remove a blade member as when the point 17 of thelatter becomes dull, it is only necessary to place the hammer upon asmooth flat surface. and tilt it forwardly by the use of the handle 6which gives the necessary leverage, the point 17 of the blade memberbeing in engagement with the hard flat surface. This operation which iswell illustrated in Fig. 2, forces the outer extremity of the spring 21far enough upwardly, to permit the insertion of the pin or nail 25, bypassing the same transversely through the eye extremity 21 of thespring, or by inserting it in the mouth 23 of the eye 21 which issufficiently open for the purpose. It is intended that this eye shall beopen sufiiciently to permit the dropping of the nail or pin thereintowhen the outer extremity of the spring is forced outwardly to theposition shown in Figs. 2 and 3. This is a quicker method of insertingthe pin, than by passing it endwise through the eye, though eithermethod may be employed. It is, however, practicable to leave the eyesufficiently open in the rear to permit the dropping of the pin or nailinto place, and at the same time have its free extremity turn into suchposition that when the pin or nail is in the position shown in Figs. 2and 3, it will support the spring in position to release the tool. Assoon as the spring is in this posi tion, the manner of removing the dullblade member and the substitution of a sharp one will be readilyunderstood. As soon as the sharp one is in place, a slight additionalmovement of the outer extremity of the spring, in the releasingdirection and accomplished in the same manner as heretofore described,will loosen the nail or pin 22 thus permitting its easy removal, afterwhich as soon as the force applied for releasing the nail, ceases toact, the spring 18 will resume its normal position in engagement withthe blade member whereby the latter is held securely in place.
